CASTING DEVICE.

Specification of Letters Patent.

Patented J an. 16, 1911.

To all whom it may concern:

Be it known that I, WILLIAM E. PATE, a citizen of the United States,residing at Garysburg, in the county of Northampton and State ofNorth-Carolina, have invented certain new and useful Improvements inCasting Devices; and 1 do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in casting devicesand the principal object of the invention is to provide a device whichis particularly adapted for use in babbitting bearings.

Another object of the invention is to provide a holder for supportingthe bearing boxes to be babbitted in such a position that they will beclamped around a core of the size of the shaft or axle so that uponpouring the Babbitt metal in place the same will be cast about the core.

Another object of the invention is to provide a novel means forsupporting the core in position and insuring the same being centered atall times.

A still further object of the invention is to provide an adjustableholder for the bearing boxes which may be arranged to receive boxes ofdifferent sizes and will work equally well with a small or large box.

With these and other objects in view the invention consists in the novelcombination and arrangement of parts which will be fully set forth inthe following specification and accompanying drawings, in which Figure lis a perspective view of a mold constructed in accordance with thisinvention, Fig. 2 is a longitudinal sectional view through Fig. 1. Fig.3 is a fragmentary transverse sectional view through the core and theboxes. Fig. 4: is a horizontal sectional view on line H of Fig. 2, andFig. 5 is a detail perspective View illustrating the babbitted box.

Referring to the drawings the numeral 1 designates the main bar of themold consisting of the central rectangular body portion 2 provided withcylindrical threaded ends 3. These ends 3 are adapted to have the wingnuts 4 threaded thereon by means of which the U -shaped supportingframes which will be more fully hereinafter denuts 17 in order that thefaces of the wing nuts to scribed are adjusted. Formed centrally of thebar 1 is an enlarged portion 5 having a central aperture 6 formedtherein the use of which will appear as the description proceeds. Asuitable collar 7 extends upwardly from the enlarged portion 5 andsupports at its upper end the centrally apertured disk 8 as will beclearly seen upon reference to Fig. 3.

The supporting frames hereinbefore referred to are designated generallyby the numeral 9 and each of said frames comprises the horizontal bightportion 10 formed with the inner and outer upstanding arms 11 and 12respectively. The inner arm of each frame is formed near its upper endwith a rectangular aperture 13 through which the rectangular portion 2of the bar 1 is slidable while the outer arm 12 of each of the U- shapedframes is provided with a circular opening 141 arranged in axialalinement with the opening 13 for the reception of the threaded portion3 of the bar 1. Formed adjacent the upper end of the arm 12 are suitableopenings 15 for the reception of the clamp bolts 16 by means of whichthe supporting brackets for the clamp screws of the boxing sections arevertically adjustable. These bolts 16 are provided with the wingadjustment may be readily made.

The supporting brackets for the clamp members hereinbefore referred toare designated generally by the numeral 18 and each comprises a Ushapedframe designated by the numeral 19 which comprises a bight portion 20having extending upwardly therefrom the arms 21. These arms terminate attheir upper ends in the outwardly extending arms 22 which project atright angles from the arms 21 and in a plane with the U- shaped frame19. F crmed at the extreme outer ends of the arms 22 are the forwardlyextending arms 23 which project at right angles to the plane of theframe 19 and are formed at their outer ends with the eyes 24 throughwhich the ends of the threaded rod 25 extend. This rod is provided atopposite ends with suitable nuts 26 between which the eyes 24: areclamped. Suitable wing nuts 27 are threaded on the rod 25 and washers28are arranged to bear against the inner provide a clamping means forthe bearing boxing.

The central core of the device is formed by cutting a section of a shaftto the proper length and providing the same with suitable threadedstems. The sections are designated respectively by the numerals 29 and30 and their threaded stems are respectively designated by the numerals31 and 32. The stems are assembled as illustrated in Fig. 3 and when inassembled position a suitable separating plate 33 is secured between thesections by suitable screws 34 or in any other desired manner. Like thelower end of each section 29 and 30 the upper ends thereof arerespectively provided with the threaded extensions-35 and 36 as will beclearly seenupon reference to Fig. 3. These extensions 35 and 36 areadapted to receive a suitable'wing nut 37 by means of which the invertedU-shaped pressure yoke 38 is forced downwardly on the upper ends of thejournal bearing sections. A spring 39 is positioned on theupper end ofeach of the sections 29 and 30 and surrounds the extensions 35 and 36and this spring is adapted to normally tend to move the yoke 38 upwardlyand out of engagement with the boxing sections. In order to support thecore in place, the threaded cylindrical portion on the lower end thereofconsisting of the sections 31 and 32 is passed through the opening 6 ofthe bar 1 and a wing nut 40 is threaded on the extension in such amanner as to firmly clamp the same in place. Before placing the wing nutin position however, a suitable washer 41 which may be of any preferablysoft material of a fabric nature is placed on the upper side of the disk8 and forms a rest for the lower ends of the bearing boxes.

The bearing boxes hereinbefore referred toare constructed in theordinary manner and consist of the arcuate portions 42 having theflanges 43 formed at its edges which flanges are preferably apertured asat 4A to receive the bolts by means of which the boxes are clampedtogether when the bearing is in use.

. In use it will be seen that the core is first placed in position inthe manner illustrated in the drawings and it will be apparent that thesame will be centered with relation to the apparatus. The boxingsections are then placed in position by standing the same upright on thecushioning washer 41. The Wing nut 37 is then turned so as to move theyoke 38 downwardly so as to insure the bearing boxes of properly sittingon the cushioning washer 41 and after this has been done the wing nuts 4are turned to move the frames 9 inwardly toward the core until thethreaded bars 25 engage the edges of the flanges 43 of the boxingsections after which the wing nuts 27 are turned up until theboxingsections are then secured in place. \Vhen in this positionit willbe seen that the boxing'sections will be-supported in spaced relation tothe core and upon pouring in the Babbitt metal the space will be filledand the inner face of the metal will conform to the shape of the corethus insuring a proper lit and eliminating the necessity of machining.

In order to provide a means for holding the device upright suitable feet4E5 are pivoted or otherwise attached to the bars 10.

l-Vhile in the foregoing there has been shown and described thepreferred embodiment of this invention, it is to be understood that suchchanges may be made in the combination and arrangement of parts as willfall within the spirit and scope of the invention as claimed.
